Error while posting IDOC data to S4 system from CI

 IDocs are not posted to S4Hana system and getting this below error:

Error Details in CI: (No further logs in CI)

org.apache.cxf.binding.soap.SoapFault: Unknown error occured in the IDoc inbound processing.

Check the mapping, it might be missing with the IDOC structure which is not populating all the fields

Example:

 IDOC @BEGIN="1"

 if missing to add this constant as "1" on mapping  that will not work.. Like wise SEGMENT aswell.

Hope this Helps!
